I heard you use wet tissue and stuff it till it pops out, does this work?

I used wet run-of-the-mill A4 paper and a socket that was the same size of the ID of the bearing. Just keep packing the paper in, tapping it down with the socket, and eventually it'll pop the bearing out.

You can also just do the above method with grease which is normally faster, but I have had more success with paper as grease tends to work its way through the bearing and pop out the cover/seal thingo. Also grease is faaaaar messier.

x2 for the wet paper, heaps goes in but it only takes 15min max.
And less mess than grease!

im intrigued by this paper method .. do you just keep stuffing it and it forces its way out from behind ?

thats incredible !

i have a special attachment i made for a mig welder like a slide hammer but for tacking inside small diameter bushes and bearings.

im so keen to give this a try .

You fill the cavity with the paper or grease and when you put enough in there and compress it with the hit of something that is the same ID as the bearing all the pressure has to go somewhere so it pops the bearing out.

I tried that method once. The grease just pushed its way through the bearing cage. What did I do wrong?

I seen a guy use a 12mm dynabolt and pulling hammer with success before.

Depending on how long it's been there and how it was put in too I guess. Dynabolt sounds good too.

Grease is the method I use. If you've got an old 12mm trailing arm bolt lying around just chop the threaded part off and it leaves you with a nice 12mm drift to use once you pack all the grease in there. You may need to re-pack more grease to complete process.

I just find a socket that matches the bearing OD and bash it out the side that doesn't have the retaining lip with a hammer :/
This is assuming the flywheel's not attached to the engine of course...

Fly on or not, it's kind of hard to bash a bearing through the crank shaft till it pops out. Might be there for a while.

Ah, so a 4A spigot's in the crank? Like a Magna? Fair enough :P
Carry on :)

Use a thread cutting tap, i can't remember what size, but use one with an extra 2 or 3 mm on the inside diameter of the spigot bush, wind it in and it will bottom out on the back of the crank, keep turning and it will eject the bush. I tried the grease trick but tap will surely work.
